Maria drove for 1.8 hours. To explain: Let a represent Carlos's driving time and b for Maria's. They together traveled 233 miles in a total of 4.4 hours. The equations we constructed indicated that a + b = 4.4. Given their speeds, we use another equation, 55a + 50b = 233. After substituting to solve, the results show that Maria's driving time equated to 1.8 hours.

Assign x as the hours Carlos drove and y as the hours Maria drove. The first equation is x + y = 4.4, from which we derive x = 4.4 - y. The second equation, representing their distances, is 55x + 50y = 233. Substituting the first equation into the second gives us 55(4.4 - y) + 50y = 233, resulting in a distance traveled of 3.5 m by Carlos in 2.6 hours.

Mario walked at a rate of 2/3 miles every 10 minutes what is his unit rate every mile per hour
AnnZ [11884]

Mario has a unit rate of 900 miles/hour.

Explanation:

It is given that Mario travels at a rate of 2/3 miles every 10 minutes.

We use the relation between speed, time, and distance, described by

\text{Speed}= \frac{\text{Distance}}{\text{Time}}

We have,

Distance = \frac{2}{3} \text{ miles}

Time = 10 minutes

By substituting these values into the preceding formula, we get

\text{Speed} = \frac{2/3}{10}\\\\ \text{Speed} =\frac{2}{10\cdot 3}\\\\ \text{Speed} =[tex]\frac{1}{15} \text{ miles/min}[/tex]

To express the unit rate in miles per hour, we must multiply by 60.

Thus, the resulting unit rate is

\frac{1}{15} \times 60\\ = 4 \text{ miles/hour}

Kayla has a bowl of beads that contains 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. She randomly draws a
AnnZ [11884]
Count the total colors of beads

42+28+12+18=100

Next, calculate the sum of the yellow and green beads

42+28=70

To determine the count of beads that are neither yellow nor green, subtract from the total

100-70=30

The first answer thus is 30/100 -> 3/10 -> 30%

Now, tally the red and green beads

28+18=46

Thus, the next answer is

46/100 -> 23/50 -> 46%

You are hiking and trying to determine how far away the nearest cabin is, which happens to be due north from your current positi
PIT_PIT [11868]

Answer:

The cabin is located 567 yards away.

Step-by-step solution:

The bearing angle of 21.2° corresponds to the interior angle near the cabin in the triangle.

Apply the tangent function:

Opposite side length: 220 yards

Adjacent side length: x (distance to cabin)

tan(21.2°) = opposite / adjacent

tan(21.2°) = 220 yards / x

Multiply both sides by x:

x × tan(21.2°) = 220 yards

Isolate x:

x = 220 yards / tan(21.2°)

x = 220 / 0.388

x = 567 yards

Hence, the cabin is 567 yards away.

a sign says that the price marked on all music equipment is 30% off the original price you buy an electric guitar for sale price
PIT_PIT [11868]

The original price stands at $450.

Step-by-step explanation:

Step 1:

Given information, Discount%, D% = 30 and Selling Price, SP = $315

Step 2:

Formulate the equation for determining the Original Price

Selling Price (SP) = Original Price (OP) - Discount (D)

Discount (D) = Original Price (OP) * (D%/100)

Step 3:

Plug in the known values into the formula

315 = OP - D

D = OP \times30/100

D = 0.3 OP

Step 4:

Insert the value of D back into the initial equation

315 = OP - 0.3 OP

315 = OP (1 - 0.3) = 0.7 OP

A resulting Original Price of OP = 315/0.7 = $450
